LGCY-21/13.5 type diesel mobile screw air compressor
1．Reliable hydraulic pump set easy for maintenance
Motor drive pump group juxtaposed outside the oil tank.The oil pump connected with motor by soft characteristics and can freely dismantle, also make the oil pump working stable ant reliable, maintaining convenient and efficient.

2. Powerful feeding and rotating system
Promote reducer drives adopt turbine and worm, which have a big push-pull effort and can reliaze self-locking. By adjust the press of the reducing valve, push-pull effort and lifting speed can adjust at will according to needs Slewing reducer drives adopt planet wheel, rotate speed is slow and torque is large. By adjust the press of the slewing reducer, the rotate speed and torque can adjust at will according to needs, and guarantee the best efficiency of down-hole and hammer drilling.
